We divide 852951 by 20
We want to figure out the number of times 852951 can be divided by 20.

Moving on to step 1:
8 divided by 20 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 20

On to step 2:
20 goes into 85 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 80 from 85 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 20

Going ahead to step 3:
The number 20 fits into 52 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 40 away from 52, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 20

Advancing to step 4:
20 can be fit into 129 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 426.0
Subtract 120 from 129 to get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 20

Step 5:
When dividing 95 by 20, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4264.0
Deduct 80 from 95 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 20

Advancing to step 6:
151 divided by 20 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 42647.0
If we take 140 away from 151, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 42647.5
If we take 100 away from 110, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 42647.55
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 42647.55, with a leftover of 0.0.
